Application filed October 26, 1914. Serial No. 868,785.

To all whom 'it may concern.'

Be it known that I, CHARLES A. KETTERER, a citizen of the United States, and resident of East St. Louis, Illinois, have invented certainA newand useful Improvements in Refrigerators, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings,l forming a part hereof.

My .invention relates to improvements in refrigerators, in which there is a single container for ice and salt through which there are extended open ended iues exposed to the ice and salt and in which container there are openings in the outer walls thereof to provide for the overflow of the salt laden Figure 1 shows in longitudinal, sectional elevation, a. refrigerator of the display case type, embodymg my 1mprovements;

and Fig. 2 is a sectional plan taken on the lin." 2-2 of Fig. 1. i

Referring byrnumerals to the accompanying drawings, 3 designates the refrigerator body, which has extending therefrom one or more display cases 4. l'Ihis refrigerator body and the display cafses are both constructed with insulated walls of any approved design. By preference and as illustrated, the display cases have in their fronts glazed panels. p l

In order to provide for access to the display cases, there are hinged doors 5; in the fear of each case, and in order to provide for cleaning the refrigerator body and removing the ice container 6, there are the hinged doors 7 in the rear of the refrigerator body. For filling the container with ice and salt, I provide in the top of the refrigerator a hinged cover 8.

Each of the display cases is in open, direct communication with the. refrigerator body, and in order to promote circulation of air currents between the refrigerator body and the display cases, I provide the deflectors comprising a horizontal partition 9 spaced fromthe upper wall of each display case and extending from the refrigerator body to a point approximately onethird the length of the display case, and a vertical partition 10 extending from the partition 9 to a point affording ample space for air circulation between the refrigerator body and the display cases.

The ice container 6 is preferably constructed of sheet metal and of hopper shape, that is substantially rectangular in plan, and itsend Vwalls converging to a point forming the inclined walls 11 in which openings are formed to receive the metallic flues ,one wall of the container to the other and through each flue. p

14 designates a removable cover for the container which is 15 registering with the flues, whereby to conserve ice by inclosing it against exposure, yet permit free circulation of air through the flues. In the top of each Hue I arrange a. section of screen wire 16, in order to pre- -vent ice dropping therethrough when filling At a point I" arrange which vexthe container around the flues. adjacent the inclined Walls 11 a row of overiiow openings 17,

provided with openingsA tends around the entire container and eachV Hue, and through which the salt laden water from the container flows onto the outer surfaces of the container and fines for the purpose of preventing a collection of frost, thereby greatly addingV to the efhciency of the ice container. In refrigerators of this type the ice vand salt and the brine resultant therefrom reach a much lower temperature than the freezing point, and I find by keepingl the outer surface of the container free from frost the refrigerator reaches a much lower temperature. The container isprovided with supporting legs 18, and for purposes provide-a cock f y, ,1052 20 designates a pan resting on the bottomA of draining the container I 19 in the bottom thereof.

of the refrigerator body, beneath the entire ice container, and is arranged to receive the salt laden water from the overflow openings in the container and conduct it away from the refrigerator through the pipe 21.

InI? ig. 1 I have shown arrows indicating i the course of air through the refrigerator body and display case.

It will be observed that the intake ends ofthe iues are considerably above'the tops of the display cases and that the refrigerator body is of greater height than the display cases, wherebyy to draw-thewarm air constantly out of the ldisplay c ases and direct it through theues to the bottom of the refrigerator'body and display cases. The 'partitions assist in the separation of the cold and warm currents-of air. y

Having thus `described my invention, what I claim as new therein and desire to secure by Letters Iatent lof the United States is v1. In arefrigerator, a salt and ice con tainer'havin'g a hopper shaped bottom, and open endedvertical tubes extended through thecontainer and bottom, there being-overflow openings formed in the walls of said container and tubes, whereby salt laden water from the container flows over .the

outer surface of said hopper bottom and over the inner faces of said tubes to prevent the collection of frost on said surfaces.

2. In combination with a refrigerator having means therein for causing air to circulate from its central portion outwardly along its bottom and thence inwardly along its top, asalt Aand ice container having a hopper shaped bottom and open-ended vertical air tubes extended therethrough, a cover over the salt and ice container having openings therethroughregistering with said air
